微信请求wx.request之GET***/index.php/Index/index/hello 500 (Internal Server Error)

今天在搭建微信小程序框架后台服务时（linux+apache+thinkphp5），部署完就随便写了个

namespace app\index\controller;

use think\Db;

class User
{
    public function index(){}
	public function hello(){
		echo "hello";
	}
}

然后postman访问，正常，简简单单的打印出hello（= =|||打印出什么其他的就错了）
然后测试小程序，没想到还真出问题了。

报了个500 (Internal Server Error)，但是可以看到下面的却是有返回“hello”的。

http 500内部服务器（HTTP-Internal Server Error）错误说明IIS服务器无法解析ASP代码

打开远程控制查看linux，查看了下access_log和error_log都没有异常记录，ssl_error_log才发现

问题很明显了，Permission denied，对于runtime下的log文件failed to open stream，用户没权限操作。
查看runtime文件夹信息：

所属用户是thain，而我们访问是apache来调用的(我用的是apache，这里根据自己情况修改，实在不懂又懒777我也无话可说），所以将所属用户改为apache：

chown -R apache runtime

重新进行访问，正常了！
